如何正确地将某些python代码重新写入php

DrchronoAPI提供了python中用于上载医疗文档的示例代码

下面是python中的示例

import datetime, json, requests

headers = {
    'Authorization': 'Bearer ACCESS_TOKEN',
}
data = {
    'doctor': 1234,
    'patient': 5678,
    'description': 'Short document description here',
    'date': '2014-02-24',
    'metatags': json.dumps(['tag1', 'tag2']),
}
with open('/path/to/your.pdf', 'rb') as f:
    files = {'document': f}
    requests.post(
        'https://drchrono.com/api/documents',
        data=data, files=files, headers=headers,
    )

根据Drchrono API，内容类型存在几个缺陷： 仅支持使用创建或更新嵌套对象以及创建多个对象 应用程序/json内容类型

仅使用表单/多部分内容类型支持文件

这是我的问题：

我正在尝试将上述代码重新写入php，以便按照此处的示例代码将文件上载到API

但这会带来错误

{"document":["The submitted data was not a file. Check the encoding type on the form."]}.

这是密码

form.php

<form method="post" action="document_upload.php" enctype="multipart/form-data">
    <input type="text" name="doctor" value="2846">
    <input type="text" name="patient" value="91189">
    <input type="text" name="description" value="Patient Medical History Form">
    <input type="text" name="date" value="2015-11-02">
    <input type="file" name="document">
    <input type="submit" name="submit" value="Upload">

$fsize = $_FILES['document']['size']; 
$ftmp = $_FILES['document']['tmp_name'];
$fname= $_FILES["document"]["name"];
$tok='my-token-goes here';
$doctor =$_POST['doctor'];
$patient =$_POST['patient'];

$data_params= array(
'document' => $ftmp,
    'doctor' => $doctor,
    'patient' => $patient,
    'date' => "2015-11-02",
    'description' => "Patient Medical History File"
); 



$url ='https://app.drchrono.com/api/documents';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, TRUE);
//curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Bearer $tok", 'Content-Type: application/json'));  
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Bearer $tok"));  

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_params);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$output = curl_exec($ch); 

echo $output;
